Ben Glisan, a former company treasurer now serving a five-year sentence and who made a good government witness in the Nigerian barge case, is on the list.

Noticably missing from the list are Michael Kopper, a Fastow protege who also pleaded guilty, and David Duncan, the former Arthur Andersen partner on the Enron case, whom the government recently agreed to stop prosecuting when it gave up on the case against the company.

On Thursday, defense attorney Reid Weingarten said he thinks Duncan would make a good defense witness, except the prosecution can always threaten to recharge him — so Duncan would likely just take the Fifth Amendment.
